Computer-aided design (CAD) tools are frequently employed to verify the design objectives before the fabrication of an integrated circuit. An important circuit parameter that requires accurate characterization is the power consumption due to the strict constraints on the acceptable power envelope of integrated systems. Circuit simulators typically provide built-in functions to measure the power...

We have demonstrated a chip-based diagnostics tool for the quantification of metabolites, using specific enzymes, to study enzyme kinetics and calculate the Michaelis-Menten constant. An array of 256×256 ion-sensitive field effect transistors (ISFETs) fabricated in a complementary metal oxide semiconductor (CMOS) process is used for this prototype. We have used hexokinase enzyme reaction on the...

Electronic devices and their highly integrated components formed from semiconductor crystals contain complex three-dimensional (3D) arrangements of elements and wiring. Photonic crystals, being analogous to semiconductor crystals, are expected to require a 3D structure to form successful optoelectronic devices. Here, we report a novel fabrication technology for a semiconductor 3D photonic cryst...

The objective of this research is to develop built-in testing (BIT) techniques for the functional verification of analog and RF circuits and systems. The aim is to avoid the use of external analog instrumentation so that the cost of testing is reduced. The major challenges addressed by this work are: (1) To develop techniques for the on-chip test of integrated RF and analog circuits through a f...

Aim – To discuss why adult patients continue to unnecessarily die. Background Healthcare professionals are failing to recognise signs of physiological deterioration. As a result adult patients are unnecessarily dying. This is despite international healthcare policy requiring healthcare professionals are appropriately trained to recognise the deteriorating adult patient. Design – A discussion pa...

To appropriately utilize the rapidly growing amount of data and information is a big challenge for people and organizations. Standard information retrieval methods, using sequential processing combined with syntax-based indexing and access methods, have not been able to adequately handle this problem. We are currently investigating a different approach, based on a combination of massive paralle...

Embedded sensor platforms can dissipate most of their energy in accessing sensor integrated circuits such as gyroscopes. But the algorithms which process the sensor data and the humans who consume the overall output of the system may often be able to tolerate some amount of error in the retrieved sensor values. Because devices are accessed through interfaces provided by system software, exploit...

This article introduces an innovative design of a low-pass (LP) negative group delay (NGD) integrated circuit (IC) in the 180-nm CMOS technology. The LP-NGD is inductorless topology constituted by RC-network with metal-insulator-metal (MIM) capacitor and polygate resistor. methodology illustrated considering chip layout process. Then, first run simulation performed rule check (DRC) 2.5 mm <inli...
